Click Event - URL Field

You can implement a custom click event and in that event choose 'Run AJAX snippet' and in that snippet use displayPopup() function to open URL in popup.

Thanks for this info. What is the correct syntax to reference the database field with the URL in it?
var win = Runner.displayPopup( {

url: "DATABASEFIELD",

width: 700,

height: 500,

});

See code examples at the end of this article, they show how you can access field values in ClientBefore and ClientAfter event:

OK, so the following Ajax Snippet works on a List View text field to open the URL in the Certificate field...
var win = Runner.displayPopup( {

url: row.getFieldValue("Certificate"),

width: 800,

height: 1000,

header: 'GIA Grading Report',

footer: '<a href="#" onclick="window.win.close();">Close window</a>',

afterCreate: function(win) {

window.win = win;

}

});

return false;
.. but this only works if the Certificate field is included in the List View. I'd like to hide the Certificate field, is there a way to reference a database field not on the List View?
Thanks

Try keeping it in the list view, but delete the field column in the editor. This has worked in that situation for me before. If it doesn't work, you can always reset the page.

Did not think of that.
Thanks!
